Device-independent quantum secure direct communication (DI-QSDC) can relax the
security assumptions about the devices' internal working, and effectively enhance QSDC's …

Quantum secure direct communication (QSDC) can directly transmit secure messages
through quantum channel without sharing keys. Three-party (3P) QSDC enables two …

We propose a three-party quantum secure direct communication (QSDC) protocol with
hyperentanglement in both spatial-mode and polarization degrees of freedom. The secret …

Measurement device-independent quantum key distribution (MDI-QKD) protocols are
immune to all possible attacks on the photon detectors during quantum communication, but …

Hyperentanglement, the simultaneous entanglement in more than one degree of freedom
(DOF), plays an important role in quantum communication and quantum information …

Hyperentanglement, defined as the entanglement in several degrees of freedom (DOFs) of a
quantum system, has attracted much attention recently. Here we investigate the possibility of …

Hyperentanglement is a promising resource in quantum information processing, especially
for increasing the channel capacity of long-distance quantum communication …

It is well known that a parallel quantum computer is more powerful than a classical one. So
far, there are some important works about the construction of universal quantum logic gates …

This study proposes the first high-capacity quantum secure direct communication (QSDC)
